MongoDB unknown metrics

[klowet]

Hi

This morning, all my monitored MongoDB nodes are in a warning state. Buth the nodes are working fine, it seems to be a Zabbix false positive.
When I get a Zabbix debug log from one of the nodes, I get this:

All other Zabbix monitoring data is collected just fine.

[HASHTAG="t4841"]zabbix_agent2[/HASHTAG] --version

[HASHTAG="t146"]zabbix_server[/HASHTAG] --version

Thanks

it seems like it is related to this bug: https://support.zabbix.com/browse/ZBX-21272

[Frits Bijlenga]

The mongo plugin is no longer in the agent2 package from version 6.0.6. Can this be added again into a new version?
/etc/zabbix/zabbix_agent2.d/plugins.d/mongodb.conf is missing

Is there any information when template: "Template DB MongoDB node by Zabbix Agent 2" will work with zabbix-agent2 ? https://support.zabbix.com/browse/ZBX-21272 is still in "elaborating" status. Still don't work with mongo v5.0.10.
